CTS Cable: It Saves A Lot More Than Money



Welcome to Enertechnos

Enertechnos was founded in 2014 expressly to develop more efficient cables for distribution grids. The initial driver was that losses in the UK grid (presently around 27TW per year according to the annual DUKES report) represent 1.5% of the UK’s total CO2 emissions. It is axiomatic that whenever the question involves ‘decarbonisation’ the answer involves ‘electricity’.

One of the chief causes of losses in grids is the cabling itself. Enertechnos has invented a cable called ‘Capacitive Transfer System’ (CTS) that presents as a long linear capacitor. In testing, the cable has been found not only to have lower losses but also greater carrying capacity per unit of conductor and other benefits such as reactive support and filtration of harmonics.

Advantages of CTS

Lower delivery losses

Resulting in lower generation costs and carbon emissions. Up to 20% more power deliverable via CTS than with conventional cable from same power source (subject to power input and load factors)

Lower capital costs

Reduced need for AC booster transformers or HVDC converter stations which can comprise up to 40% of project capex, since CTS has materially less voltage drop than existing wire and cable

Lower ongoing operating costs

Reduced maintenance requirements owing to fewer transformers and converter stations on longer runs

Expected lower earth leakage

Where pylons are unwelcome, CTS can enable longer cable-runs underground while still delivering useful power

Reactive Support

CTS’s series capacitance supports the system voltage, reducing the need for reactive power to support renewable generators

The electricity sector is going through a major transformation

The ways in which electricity is generated and consumed has changed dramatically over the last decade and this transition is expected to continue. The transmission and distribution of electricity is a fundamental part of the electricity value chain.

UK National Grid’s Future Energy Solutions (FES) annual predictions on electricity peak demand in 2050 have been increasing year-on-year. These trends point to a growing demand in energy. Bloomberg expects that by 2050, peak energy demand will increase by 170% globally from today’s figure. To support this, around $14 trillion of global grid investment is forecast and an exponential growth of renewables is foreseen.

CTS is a breakthrough and potentially disruptive technology: the first fundamental change to power cable geometry and fabrication in decades, whilst still leveraging existing cable-manufacturing technology.
